MLB球員在合約年與非合約年效率衡量之研究
本研究以資料包絡分析法來衡量職業球員的績效表現,球員在簽訂複數年合約前後與績效表現之關聯性,來探討球員是否有合約週期的現象,進而再探究球員處於合約年的比率多寡,是否會對球隊的勝率造成影響。 本研究以2002年球季結束後至2008年球季開始前,這段期間曾與球團簽訂複數年合約的美國大聯盟球員為研究對象。實證結果顯示投手在簽訂複數年合約前一年,純粹技術效率有明顯增加,野手部分則顯示在簽約前兩年整體技術效率呈現顯著增加。研究結果顯示支持合約週期理論,即球員在合約年之前會刻意增加表現,以便爭取較佳之合約。另外,以2009年各球隊的勝場數為研究對象,實證結果顯示,當球隊中有較多投手處於複數年合約的第一...
